One of the most effective representation in VR is letting interaction that is not possible in real life happen. Learning a language can be difficult. We find it hard to practice it, especially due to the fact we usually don’t have a person around us speaking the language we are trying to learn. However, one of the most effective ways to learn language is to talk to other people.
There is a VR application that lets you learn languages through VR experience. This will let people have the interaction that we lack when we learn new languages through books. Because lots of people find learning a new language difficult, I believe that representation of VR in this area would be very helpful.
